Product details
Overview
RKZ16TWAJQE#H1 from Renesas Electronics is a bi-directional silicon planar Zener diode designed for transient voltage suppression on bidirectional signal lines, featuring 16 V nominal Zener voltage (14.5–17.5 V at 1 mA), 30 pF capacitance at 0 V, 30 kV ESD immunity per IEC 61000-4-2, and 200 mW power dissipation - deployed in automotive CAN bus protection circuits.
For engineers reviewing the RKZ16TWAJQE#H1 datasheet, RKZ16TWAJQE#H1 pinout, RKZ16TWAJQE#H1 application, or RKZ16TWAJQE#H1 equivalent, key selection criteria include bidirectional clamping capability, low capacitance for high-speed data integrity, automotive-grade surge robustness, and CMPAK package compatibility with automated SMT assembly.
Technical Context
This device operates as a symmetrical dual-Zener structure enabling identical forward and reverse breakdown behavior, supporting bidirectional transient absorption without polarity dependence. Its 30 kV ESD rating applies to both directions under IEC 61000-4-2 test conditions (150 pF/330 Ω), with failure defined as IR > 0.1 µA at VR = 12 V.
The RKZ16TWAJQE#H1 is rated for junction temperatures up to 150°C and storage from –55°C to +150°C, and its electrical characteristics are specified at Ta = 25°C with pulsed 40 ms Zener current testing to avoid thermal runaway during surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 14.5–17.5 V at 1 mA; defines clamping threshold for bidirectional overvoltage events on CAN or other differential buses. |
| Capacitance | 30 pF at 0 V, 1 MHz; ensures minimal signal distortion on 1 Mbps CAN FD or legacy CAN physical layers. |
| ESD Rating | 30 kV (IEC 61000-4-2); guarantees immunity to contact discharge in automotive cabin and under-hood environments. |
| Power Dissipation | 200 mW; limits thermal stress during repetitive transients; derates linearly above 25°C ambient per Fig.2. |
| Reverse Current | ≤0.1 µA at 12 V; maintains high-impedance standby state to avoid loading of 12 V bias networks. |
| Junction Temp | 150°C max; supports operation in engine control units and powertrain modules with elevated board temperatures. |
Pinout & Package
CMPAK (JEITA code PTSP0003ZB-A, Renesas code N8) is a 3-pin surface-mount package measuring 2.0 × 1.25 × 0.9 mm (max), optimized for high-density PCB layouts and high-speed pick-and-place assembly. The package uses a lead-free matte tin finish and weighs approximately 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Zener 1 / Cathode of Zener 2 | Common terminal for bidirectional clamping; connects to protected line (e.g., CAN_H or CAN_L). |
| 2 | Cathode of Zener 1 / Anode of Zener 2 | Second common terminal; forms symmetrical clamp pair with Pin 1 for differential line protection. |
| 3 | Substrate / Heat Sink Pad | Thermally conductive exposed pad; must be soldered to PCB copper pour for thermal management and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Clamping | Symmetrical Zener structure enables identical forward/reverse breakdown (VZ ≈ 16 V both ways), eliminating need for back-to-back discrete diodes. |
| Automotive Compliance | Qualified per AEC-Q101 stress tests and supports automotive applications including body control modules and infotainment gateways. |
| Low Capacitance | 30 pF maximum ensures <1% signal rise-time degradation on 125 ns CAN edges, preserving bit timing integrity. |
| High-Density Packaging | CMPAK footprint (2.0 × 1.25 mm) saves >40% board area versus SO-8 or SC-70 alternatives while maintaining thermal performance. |
Applications
| Automotive CAN Bus Protection | Industrial RS-485 Transceivers |
|---|---|
Use Scenario: Protecting high-speed CAN FD interfaces in electronic control units against load dump, ESD, and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS diode placed directly at connector entry point to clamp transients before reaching CAN transceiver IC. Use Value: Prevents latch-up or permanent damage to CAN PHY while maintaining <30 pF loading to preserve 5 Mbps signal fidelity. | Use Scenario: Safeguarding half-duplex RS-485 nodes in factory automation systems exposed to ground loop surges and cable coupling noise. IC Role / Device Role / Timing Role: Line-side transient suppressor across differential A/B bus lines, referenced to local ground plane via Pin 3 thermal pad. Use Value: Enables reliable 10 Mbps data transmission over 1200 m cables by limiting overshoot to <20 V without distorting differential swing. |
| USB 2.0 Data Line ESD Guard | Smart Sensor Interface Protection |
Use Scenario: Adding secondary ESD protection on D+/D− lines downstream of integrated USB transceiver ESD structures in automotive telematics modules. IC Role / Device Role / Timing Role: Secondary clamping device absorbing residual 30 kV HBM events that exceed internal transceiver tolerance. Use Value: Extends system-level ESD robustness beyond IEC 61000-4-2 Level 4 without degrading 480 Mbps eye diagram margin. | Use Scenario: Shielding analog/digital sensor outputs (e.g., pressure, temperature) in battery management systems from board-level ESD and switching noise. IC Role / Device Role / Timing Role: Low-leakage (≤0.1 µA) shunt protector on single-ended sensor supply or output lines operating at 3.3 V or 5 V. Use Value: Maintains sensor accuracy by preventing IR-induced offset shifts while surviving repeated 15 kV air-discharge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional Zener TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF15CA | 15 V nominal VZ (13.3–16.7 V), 35 pF, DO-219AB package (2.2 × 1.35 × 0.9 mm) | Higher capacitance and larger footprint; lower ESD rating (20 kV IEC 61000-4-2) | Acceptable where board space allows and 30 kV ESD is not mandated. |
| TPD2E001DRYR | Two-channel unidirectional array (5.5 V VBR), 10 pF/channel, 6-pin X2SON | Unidirectional only; requires external series resistor for bidirectional use; lower clamping voltage | Preferred for low-capacitance USB or I²C protection but not direct replacement for CAN bus symmetry. |
Compared with SMF15CA and TPD2E001DRYR, the RKZ16TWAJQE#H1 uniquely delivers certified 30 kV bidirectional ESD immunity in a compact CMPAK package with matched Zener thresholds - making it optimal for automotive CAN and industrial differential bus protection where symmetry and high surge margin are mandatory.

FAQ
What is the exact Zener voltage range for RKZ16TWAJQE#H1?
The RKZ16TWAJQE#H1 has a guaranteed Zener voltage range of 14.5 V to 17.5 V when tested at 1 mA with a 40 ms pulse, per the R07DS0170EJ0100 datasheet. This specification applies to both forward and reverse conduction due to its symmetrical bi-directional structure, ensuring consistent clamping behavior on differential signal lines like CAN_H/CAN_L.
Does RKZ16TWAJQE#H1 meet automotive qualification standards?
Yes, the RKZ16TWAJQE#H1 is qualified per AEC-Q101 for stress testing and supports automotive applications including body control modules and infotainment gateways. Its design complies with IEC 61000-4-2 (30 kV contact discharge) and meets requirements for surge immunity in ISO 7637-2 environments, as confirmed in Renesas' preliminary datasheet R07DS0170EJ0100.
How is the thermal pad (Pin 3) of RKZ16TWAJQE#H1 intended to be used?
The exposed thermal pad (Pin 3) of RKZ16TWAJQE#H1 must be soldered to a PCB copper pour for effective heat dissipation and EMI suppression. It serves as the substrate connection and improves thermal resistance by up to 40% compared to non-thermal-pad packages. Renesas recommends minimum 3×3 mm² copper area with ≥4 thermal vias to inner ground planes for sustained 200 mW operation.
Can RKZ16TWAJQE#H1 replace a pair of discrete 16 V Zener diodes in anti-parallel configuration?
Yes, RKZ16TWAJQE#H1 is functionally equivalent to two 16 V Zener diodes connected anode-to-cathode, providing identical bidirectional clamping in a single CMPAK package. Its symmetrical VZ (14.5–17.5 V both ways) and matched leakage (<0.1 µA at 12 V) eliminate matching tolerances and reduce PCB footprint by >60% versus discrete solutions.
What is the maximum operating temperature for RKZ16TWAJQE#H1?
The RKZ16TWAJQE#H1 has a maximum junction temperature (Tj) rating of 150°C and a storage temperature range of –55°C to +150°C. Its power dissipation derates linearly above 25°C ambient, with full 200 mW capability only at Ta ≤ 25°C - as shown in Fig.2 of the R07DS0170EJ0100 datasheet.
